In the diagram below, an and bc are tangent to o. which equation could be solved to find x, the measure of ac

There are three ways I know offhand to get x. Since the total circle is 360 degrees, x=360-238=122 degrees. Since quadrilateral BAOC has two right angles the other two angles are supplementary, x=AOC=180-58=122 degrees.

The third way is the rule they want you to recall here: Angle ABC is half the difference of the arcs:

Choice A, which checks when x=122 degrees.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
